How to Make Italian Penicillin Soup Recipe
Step 1: Sauté the Base Vegetables
Begin by heating the olive oil in a large pot over medium heat. Once shimmering, add the diced onion and cook for about 3-4 minutes until it’s soft and translucent, releasing its natural sweetness. Then, stir in the minced garlic alongside the sliced carrots and celery. Toss in the dried oregano, thyme, and if you’re using it, a pinch of red pepper flakes. Let everything cook together for around 5 minutes, letting the vegetables soften and the herbs bloom.
Step 2: Build the Broth
Pour the low-sodium chicken broth into the pot with your softened vegetables and bring the mixture to a lively boil. This step melds all the flavors together and starts transforming the simple ingredients into a comforting, aromatic base. As soon as it boils, lower the heat to a gentle simmer and let it stew for 10 minutes to deepen the flavor.
Step 3: Add Pasta and Protein
Next, stir in the acini di pepe or orzo pasta. Let them cook until just tender, usually about 8-10 minutes—perfectly al dente. Following this, fold in the shredded chicken and freshly squeezed lemon juice, letting it simmer for another 5 minutes. This is where the soup really comes alive: the chicken adds hearty substance while the lemon juice gives it a subtle, invigorating brightness.
Step 4: Finish with Greens and Seasoning
Lastly, stir in the fresh spinach or escarole and allow it to gently wilt, which will take about 2 minutes. Taste the soup and season with salt and pepper to your liking. These final touches bring a freshness and balanced seasoning that elevates this soup from simple to spectacular.
How to Serve Italian Penicillin Soup Recipe

Garnishes
The best part about serving this Italian Penicillin Soup Recipe is the gorgeous finishing touches. A generous sprinkle of freshly grated Parmesan cheese adds a creamy, savory note that melts into the warm broth. Top it off with chopped fresh parsley for a pop of color and a vibrant, herbaceous aroma that instantly lifts the dish.
Side Dishes
This soup pairs beautifully with crusty Italian bread or garlic breadsticks, perfect for dipping and soaking up all that flavorful broth. A simple side salad with a light vinaigrette also complements the meal nicely, balancing the warmth of the soup with crisp freshness.
Creative Ways to Present
For a cozy dinner party, serve individual bowls garnished with Parmesan and parsley, alongside small dipping plates of olive oil and balsamic vinegar for the bread. You can also ladle the soup into rustic bread bowls for an extra charming presentation that makes your meal feel special and hearty.
Make Ahead and Storage
Storing Leftovers
This Italian Penicillin Soup keeps wonderfully in the fridge for up to 3 days. Store it in an airtight container to preserve its fresh flavors and comforting textures. Just give it a good stir before reheating to redistribute those vibrant greens and tender chicken.
Freezing
If you want to save this soup for longer, it freezes well—but for best results, leave out the pasta when freezing. Pasta can become mushy upon thawing, so simply add fresh pasta when you reheat the soup. Freeze in airtight containers or heavy-duty freezer bags, and enjoy within 2 months for maximum freshness.
Reheating
When ready to eat, reheat the soup gently on the stovetop over medium heat. If frozen, thaw overnight in the fridge first. Add your pasta at this stage and simmer until perfect. Stir occasionally to prevent sticking and to reawaken the fresh lemon and herb notes.
FAQs
Can I make this soup vegetarian?
Absolutely! Simply swap the chicken broth for vegetable broth and replace the shredded chicken with chickpeas or white beans. You can also swap spinach for kale or Swiss chard to keep the hearty texture.
What pasta works best for this recipe?
Acini di pepe is traditional, but orzo or even small ditalini pasta are excellent substitutes. They all cook quickly and absorb the broth beautifully, adding that lovely, satisfying bite to the soup.

The optional red pepper flakes add just a subtle heat. You can adjust the amount or omit them altogether if you prefer a milder soup that still delivers plenty of comforting flavor.
